DRIVING MECHANISM FOR DOOR LOCK, AND DOOR LOCK

WIPO Patent Application WO/2022/068481

A1

Provided in the present application are a driving mechanism for a door lock, and a door lock. The driving mechanism comprises an electric motor, a planet gear assembly and a retainer, wherein the planet gear assembly comprises a gear ring, a planet gear and a sun gear; the electric motor is rotatably connected to the gear ring; the planet gear is rotatably connected between the sun gear and the gear ring; the retainer is arranged on one side of the planet gear assembly; the gear ring and the sun gear abut against the retainer; and the planet gear is connected to the retainer. When the sun gear is located in a fixed state, the gear ring rotates under the drive of the electric motor. When the gear ring is in a fixed state, the planet gear rotates relative to the sun gear, and the retainer rotates by means of mutual cooperation of the sun gear, the planet gear and the retainer. A door is opened and closed by means of two manners of using the electric motor to control the gear ring to rotate or enabling the sun gear to rotate, thereby adding a method for controlling the door lock, solving the problem that a door cannot be opened and closed because an electric motor is damaged in a single motor lock, and reducing the difficulty and risk of opening the door.
